Drawer unit for the study desk for my son + 2 book stands

Here are the drawers for the study desk for my son.The top piece is the series from the top from the desk. This unit basically goes underneath the desk, but it can also be right side of the desk, so the desk can be a bit wider.To make this drawer high, I made 2 books stands.

The drawer unit has 5 casters including one under the bottom drawer, and I used metal slide rails for the bottom drawer, and wooden rail for 2 top drawers. I think it’s just fine this way.Made pen tray as my son requested, it’s made of 2X4, and everything else is made of white ash.

I need to make a chair go with this, but it will be after some other projects I have to finish first.I promised to my son that I would make these by April 8th, his first day of the elementary school.I am so glad that it’s all done by then, now the next project is bed for my daughter.
